Commitment to renewable energy

Environmentally friendly with solar power, wind power and biogas

Swiss Post takes responsibility for climate protection. It uses green electricity, now operates ten photovoltaic systems, is testing new drive technologies, and has also been using biogas in Swiss Post buildings since 2014.

With its ten photovoltaic systems, Swiss Post feeds around 5,000,000 kilowatt hours of solar electricity into the grid every year.

Swiss Post obtains its electricity from 100 percent renewable energy sources from Switzerland. It is “naturemade basic” certified. Of this electricity, 5 percent is in fact “naturemade star” certified green electricity produced by wind turbines on Mount Crosin in the canton of Jura and from farms, small businesses and small ecological hydroelectric power stations.

Two new solar power plants in Härkingen

In October 2014, Swiss Post brought two photovoltaic systems on stream on the roofs of the letter and parcel center in Härkingen. With modules covering around 10,000 square metres, they are among the largest in the Swiss plateau. The systems produce up to 1,340,000 kilowatt hours of low CO₂ and renewable electrical energy each year. This is equivalent to the electricity consumption of over 380 Swiss households over the same period.

Together with the systems in Daillens, Frauenfeld, Sion, Geneva, Locarno, Giubiasco, Yverdon and Zurich-Mülligen, Swiss Post now operates a total of ten systems feeding approximately 5,000,000 kilowatt hours of solar electricity into the grid each year. By doing so, Swiss Post is also making a contribution to implementing the Confederation's Energy Strategy 2050.

Alternative drive technologies and biogas

Hydrogen, biodiesel, green electricity or biogas are increasingly used as fuel for Swiss Post's vehicle fleet. There are now five fuel cell buses, which emit only steam, on routes operated by PostBus, the first public transport company in Switzerland to use such vehicles. There are also more than 30 PostBus diesel hybrid buses operating on Swiss roads. Since the end of 2014, Swiss Post has also been using 7 percent biodiesel made from residues from edible oil production at Mobility Solutions Ltd petrol stations, saving more than 1,500 tonnes of CO₂ annually. Swiss Post operates around 5,800 electric scooters with eco-electricity. Its gas-powered vehicle fleet is one of the largest in Switzerland. More than 120 vans deliver parcels with 100 percent Swiss biogas. Swiss Post now uses 10 percent biogas for gas heating in its buildings, reducing CO₂ emissions by around 200 tonnes annually.
